Abstract

Acarrier-containing membrane has been developed which can selectively move sodium ion from a region of low concentration to a region of high concentration. The energy for this movement comes from the simultaneous countertransport of protons. The transport is unaffected by electrostatic and osmotic effects but is dominated by the chemical characteristics of the mobile carrier. Since the membrane is chemically well defined, its operation is understood on a molecular level and its behavior can be successfully predicted from a simple theory.
